Abstract
The invention belongs to the technical field of engines, and particularly relates to a motorcycle engine right bent axle box which comprises a box body. The box body is connected with a motorcycle engine right bent axle box cover. The box body is an aluminum alloy casting piece. The wall thickness of the box body is 4 mm. A reinforced rib is arranged on the side face of the box body. The multiple problems that an existing motorcycle engine right bent axle box is not reasonable in structural design so that product wall thickness is large, a product is heavy, fastening hole design is complex and the like are solved.
Description
Technical field
The invention belongs to technical field of engines, be specifically related to right crankshaft box of motorcycle engine.
Background technique
Now present, right crankshaft box of motorcycle engine adopts the cast iron materials casting mostly, and not only the wall thickness dimension of product is larger, and product is heavier, is assembled to the growth requirement that can't satisfy light in motorcycle; And fastener hole when design, need to first cast out step, could use after boring, tapping, greatly reduce working efficiency, increased the cost of production of enterprise, be unfavorable for very much long-run development and the progress of enterprise.
Summary of the invention
Purpose of the present invention: unreasonable and bring that the product wall thickness dimension is large, product is heavier and the problems such as fastener hole design trouble in order to solve existing right crankshaft box of motorcycle engine structural design, and the proposition right crankshaft box of motorcycle engine.
Technological scheme of the present invention: right crankshaft box of motorcycle engine, comprise the casing body, described casing body is connected with right crankcase cover of motorcycle engine, described casing body is aluminum alloy die casting, the wall thickness of described casing body is 4 ㎜, and the side of described casing body is provided with stiffening rib.
Right crankshaft box of motorcycle engine of the present invention, because the casing body is aluminum alloy die casting, the wall thickness of casing body is 4 ㎜, therefore the wall thickness dimension of product is very little, and the weight of product is lighter, is installed to the growth requirement that can satisfy light on motorcycle; Because the side of casing body is provided with stiffening rib, therefore guaranteed the requirement of strength of product, make product can satisfy usage requirement.
Further, described casing body is provided with fastening screw.
Because the casing body is provided with fastening screw, therefore fastening screw can straight forming during die casting, need not first to cast out step, then boring and tapping, greatly improved working efficiency, reduced the cost of production of enterprise, be very beneficial for long-run development and the progress of enterprise.
Description of drawings
Fig. 1 is the embodiment's of right crankshaft box of motorcycle engine of the present invention structural representation.
Embodiment
As shown in Figure 1, the invention provides right crankshaft box of motorcycle engine, comprise casing body 1, casing body 1 is connected with right crankcase cover of motorcycle engine, casing body 1 is aluminum alloy die casting, the wall thickness of casing body 1 is 4 ㎜, and the side of casing body 1 is provided with stiffening rib 2, and casing body 1 is provided with fastening screw 3.
In the present embodiment, casing body 1 is aluminum alloy die casting, and the material of employing is aluminum alloy, and its density is 2.7g/cm
3, and the density of cast iron is 7.8g/cm
3, like this, the weight of die cast product only have existing casting product weight approximately 34.6%, can satisfy the growth requirement of light.In fact, the product wall thickness of die cast only has 4mm, and the product wall thickness of former casting is 6mm, and this just provides good condition for the design of fastening screw 3.
In addition, the design of stiffening rib 2, consider mainly that the wall thickness of die cast product is thinner, intensity a little less than, and stiffening rib 2 can increase the intensity of product, thereby guarantees that product can satisfy usage requirement.
In addition, manufacturing procedure has been simplified in the design of fastening screw 3 greatly, and during die casting, fastening screw 3 can straight forming, need not first to cast out step, then boring and tapping, has greatly improved working efficiency, has reduced the cost of production of enterprise.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
